About this image

The comet is 825 million km away so one arcsec corresponds to around 4,000 km. The coma is now around 45 arcsec across, so around 180,000 km diameter, which is a quite a bit bigger than Jupiter. Two days ago it was around 32 arcsec diameter, or 128,000 km, so it is expanding at around 150 m/s. The structures shown in the radial gradient filter match up with those visible in a much larger telescope (see here). This is a great opportunity to follow the coma evolution after a major outburst.
